All rights reserved. The material contained herein may not be reproduced, adapted, merged, translated, stored, or used without the prior written consent of the copyright owner. The information furnished in this publication is subject to changes without notice. Brief Description The ZSPM1000 is a configurable true-digital single- phase PWM controller for high-current, non-isolated DC/DC supplies. It operates as a synchronous step- down converter in a single-rail and single-phase con- figuration. The ZSPM1000 integrates a digital control loop, opti- mized for maximum flexibility and stability, as well as load step and steady-state performance. In addition, a rich set of protection and monitoring functions is provided. On-chip, non-volatile memory (NVM) and an I 2C™ * interface facilitate configuration. The PC-based ZMDI ’s Pink Power Designer™ pro- vides a user-friendly and easy-to-use interface to the device for communication and configuration. It can guide the user through the design of the digital com- pensator and offers intuitive configuration methods for additional features, such as protection and sequencing. Features Programmable digital control loop Advanced digital control techniques Tru-sample Technology ™ State-Law Control ™ (SLC) Sub-cycle Response ™ (SCR) Improved transient response and noise immunity Protection features Over-current protection Over-voltage protection (VIN, VOUT) Under-voltage protection (VIN, VOUT) Overloaded startup Restart and delay Support for SMOD and ZCD drivers Fuse-based NVM for improved reliability Operation from a single 5V or 3.3V supply Optional PMBus™ address selection without external resistors * I 2C™ is a registered trademark of NXP. ** Subject to product type. Benefits Fast configurability and design flexibility Simplified design and integration Reduced component count through system level integration Simplified monitoring for system power and thermal management Higher energy efficiency across all output loading conditions Available Support Evaluation Kit PC-based Pink Power Designer™ Physical Characteristics Operation temperature: -40°C to +125°C** V OUT max: 5V Lead free (RoHS compliant) 24-pin QFN package (4 mm x 4 mm) ZSPM1000 Typical Application Diagram |
